Abstract

Phylogenetic relationships were examined within the genera Theobroma and Herrania using 18 species representing all recognized sections of both genera and three outgroups. DNA sequences for vicilin, a gene encoding a seed storage protein, were analyzed using parsimony. Both Herrania and Theobroma appeared monophyletic on the most parsimonious trees, but the monophyly of Theobroma was only weakly supported. The monophyly of all currently recognized sections of both genera was supported with the exception of Theobroma sect. Glossopetalum within which was nested the monotypic sect. Andropetalum. The analysis sheds light on the morphological diversification of these closely related genera and serves to demonstrate the potential phylogenetic utility of vicilin.
